2 claims. (cl. 4 52) This invention relates to a flush-valve tank-ball.

An object of this invention is the provision of an eicient and comparatively simple structure of a ball valve device for ilush tanks.

Another object of this invention is the construction of a valve device which comprises a minimum number of elements that eiiciently operate for producing a strong and etliciently operating device.

With the foregoing and other objects in View, this invention comprises certain novel constructions, combinations, and arrangements of parts as will be hereinafter fully described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims.

In the drawings:

Figure 1 is a view in side elevation of a device constructed in accordance with this invention, which device is in a closed position.

Figure 2 is a vertical central sectional view of the device.

Figure 3 is a horizontal sectional view, taken on line 3--3, Figure l and looking in the direction of the arrows.

Figure 4 is a View in side elevation of a copper tube, ball valve and L-shape bracket.

Referring to the drawings by numerals, 1 designates a valve base that has an externally threaded end 2 that may be screwed into an ordinary tank not shown. The valve base 1 is provided with a valve seat 3 for receiving the ball valve 4 when said valve is in a seated position, Fig. 1. The base 1 has a ange bracket 5 into which is screwed the lower end of overflow pipe 6. Mounted on the overow pipe 6 is a bracket 7. This bracket 7 is provided with a hub 8 on its outer end. A brass guide rod 9 is threaded at its upper end into the hub portion 8 of bracket 7.

Extending through the ball valve 7 is a copper tubing 10, which tubing is closed at its lower end, Fig. 2. The upper end of tubing 10 is open and is provided with an annular flange 11. A substantially L-shape bracket 12 is mounted on the tubing 10, against the top of ball valve 4 and under flange 11. The L-shape bracket 12 is provided with an opening 13 in which is positioned the lower link 14 of pull chain 15.

In operation, when the valve 4 is seated as shown in Figure l, when upward pull is exerted on chain 15, the valve 4 will be lifted otf of seat 3, allowing liquid in the tank (not shown) to pass out through the valve base 1. Upon pressure on chain 15 being relieved, the valve 4 will drop back into a seated position (Fig. 1), whereupon the valve mechanism will be closed.

By reason of the brass rod 9 being positioned partly in the copper tubing 10, said rod 9 will guide the tubing 10 at all times, whether in a raising action or when the ball valve 4 is moving to a seated position.

While I have described the preferred embodiment of the invention and illustrated the same in the accompanying drawings, certain minor changes or alterations may appear to one skilled in the art to which this invention relates during the extensive manufacture ofthe same, and I, therefore, reserve the right to make such changes or alterations as shall fairly fall within the scope of the appended claims.

What I claim is:

l. In a device of the class described, the combination with a valve base provided with a depending extension and a Valve seat, of a ball Valve adapted to engage said valve seat, a tubing closed at its bottom and open at its top extending entirely through and above said ball valve, said tubing having its lower end extending at all times below said depending extension, a rod having its lower end extending only a short distance into the top portion of said tubing, means supporting said rod in a fixed position on said valve base, and a pull chain and means attaching said chain to the upper part of said tubing.

2. In a device of the class described, the combination with a Valve base provided with a depending extension and a valve seat, of a ball valve adapted to engage said valve seat, a tubing closed at its bottom and open at its top extending entirely through and above said ball valve, said tubing having its lower end extending at all times below said depending extension, a rod having its lower end extending only a short distance into the top portion of said tubing, means supporting said rod in a fixed position on said valve base, an annular llange on the upper end of said tubing, an L-shaped bracket on said tubing under said flange, and a chain fastened to the outer end of said L- shaped bracket.
